In order to enhance Jc in magnetic fields for all applied angles, we fabricated multilayered films consisting of Sm1.04Ba 1.96Cu3Oy (SmBCO) layers and BaSnO3 (BSO)-doped SmBCO layers on MgO substrates (multilayered SmBCO) by the pulsed laser deposition (PLD) method. We varied the numbers of layers (8, 16, 32, and 64). In the magnetic field angle dependence of Jc (B = 1 T, 77 K), only in the 8-layer sample was Jc higher than that of pure SmBCO thin films for all applied angles. The other sample showed different Jc characteristics.
